BENJAMIN R. STEVENS, OF

GRAND RAPIDS, MICHIGAN.

CARPET-SWEEPER.

SPECIFICATION .forming part of Letters Patent No. 226,495, dated April 24, 1883.

` Application tiled February 7, 1882. (No model.)

.To all whom it may concern Be it known that I, BENJAMIN It. STEVENS,

of the city of Grand Rapids, in the county ot'4 Kent and State of Michigan, have invented certain new and useful Improvements in Carpet-Sweepers, of which the following is asp'eciiication.

My invention relates to improvements in that class of sweepers in which theH brushroller is operated by means of friction drive- Wheelsfand the objects of my invention are to increase the friction, and thereby the effectiveness of the machine, and to provide a superior method of' clearing the friction-Wheels. I attain these objects by means of the mechanism illustrated in the accompanying drawings, in which- Figure l is a perspective view of the inside of one end of the sweeper, showing the arrangement and construction of the springs which hold the journals of the drive-Wheels and other parts, more iully described hereinafter. Fig. 2 is a view similar to Fig. 1, but having the partition P in place to holdthe drive-wheels on their journals.

Similar letters refer to similar parts throughout the several views.

In the drawings,NNare two metallic springs, which support thejournals ot' the drive-wheels. Each spring N is attached at one end by means of a screw or any suitable device, as shown by I, the intent being to allow a free movement to the driving-wheel, and by constructing it in the form shown in the drawings and attaching it as above described the object is tully accomplished. S, thejournal ofthe drive-wheel, is soldered or otherwise attached to the spring. The spring may be made of steel or other suitable wire.

G G are guides or stays designed to hold the springs in place.

P P is a removable partition, which slides into the grooves M Min the sweeper-case at such a point as to bear against the inner ends of the journals S S, and is held in place by means of the spring O. The objectof this arrangement and construction ot' partition P is to enable the user to readily detach the Working parts of the sweeper from the box,in order to remove any threads or other obstacle which may become attached to the drive-wheels, and to facilitate the cleaning and oiling of the bearings. This `operation is performed as follows: Withdraw the dust-pans, remove the brushroller, and take out the partition P P. This allows of the removal of the drive-wheels from This operation requires but a moment, and'all threads and other obstructions can be readily removed.

R represents a sprin g-bearin g for the brushroller, and the roller is inserted and removed in the ordinary manner.

L L represent grooves in the case or boX of the sweeper, which receive tongues or guides on the pans, by means of which the pans may be slid horizonally into .the box when in use, and may be Withdrawn in order to empty the contents. A catch or spring may be provided, the more securely to hold the pans in place, if found desirable.

Having thus described my invention, what I claim to have invented, and desire to secure by Letters Patent, is-

In a carpet-sweeper, the combination ofthe springs N, attached to the sweeper-case, as shown at I, the guides G, to hold the springs in place, the journals S, and the drive-wheels W W, turning on said journals, and arranged as shown, so as to permit a free and unobstructed movement of the driving-wheels, substantially'as described.
